- Fire Point's FP-5 Flamingo cruise missile, shown at the Eurosatory defence expo in Paris, is guided by the open-source Ardupilot flight controller, which runs on hardware costing less than $100 and is typically used by hobby drone enthusiasts.
- Flamingo is a 6-tonne missile that carries a warhead twice as heavy as a Tomahawk for twice the distance at a fraction of the cost, reflecting Fire Point's philosophy of providing effective long-range strike far cheaper than 'exquisite Western designs,' per Roy Gardiner at Defense Tech for Ukraine.
- Fire Point CTO Iryna Terekh said open-source software offers independence from companies that could go out of business or be blocked from exporting to Ukraine, while a community of thousands of engineers quickly identifies and resolves software bugs.
- Russia's Shahed attack drones also rely heavily on commercial electronics, with a new 'Seeker' version using a UK-made Raspberry Pi 4 processor and AI software to lock onto targets, according to Ukrainian drone expert Serhii Beskrestnov.
- Ukraine's vast fleet of small drones runs largely on open-source flight controllers including Betaflight, Ardupilot, and PX4, while Russia deploys conventional high-end systems like the Kalibr alongside its commercial-electronics Shaheds.
- Gardiner warned that the dramatic reduction in cost gives many state and non-state actors access to strike capabilities previously available only to the wealthiest nations, and that expensive custom military electronics will likely survive only for the most demanding requirements.
Why it matters: Fire Point's CTO says open-source software insulates weapons development from export blocks and corporate failure — a direct hedge against the supply chain vulnerabilities that have constrained Ukraine's access to Western long-range systems. With Ardupilot running on sub-$100 hardware, the barrier to cruise-missile-class strike capability has dropped from superpower budgets to startup costs.
